Etiometry Board of Directors


Evan-ButlerEvan Butler | Board Member, President and CEO

Evan Butler is an engineer and entrepreneur who co-founded Etiometry in 2010. Previously, he worked at Boston Children’s Hospital in the Pediatric Cardiac Bioengineering Laboratory designing, building, and testing novel surgical robots and tools. Evan was also a NASA GSRP Fellow with Dryden Flight Research Center, and created intelligent flight control systems.

He received his Bachelor’s degree in Physics and Aerospace Engineering, and his Masters degree in Dynamics and Control Engineering from Boston University. Evan has published conference papers, journal articles and a book chapter in the fields of medical predictive analytics, concentric tube robots and tools for minimally-invasive beating heart surgery, and intelligent flight control systems. Evan has received multiple awards, including the 2010 IEEE Transactions on Robotics Best Paper Award.



Dimitar-BaronovDimitar Baronov, PhD | Board Member

Dimitar Baronov is a co-founder of Etiometry and leads the company’s research and development organization. He received his Bachelor’s degree from Technical University in Sofia, Bulgaria and a Ph.D. in Aerospace Engineering from Boston University. Before co-founding Etiometry, Dimitar developed a theory for optimal human-machine interaction in achieving complex tasks.

This work informed the U.S. Air Force, and provides a basis for Etiometry’s innovative approach to integrating analytics into medical care. As CTO of Etiometry, Dimitar is the lead designer of the Etiometry Platform that quantifies clinical risks based on continuous streams of physiologic data. He has also served as the Principal Investigator for several National Institute of Health grants.



Jesse-LockJesse Lock, MD Ph.D. | Board Member

Dr. Jesse Lock is the Chief Medical Officer and a co-founder of Etiometry. He received a BA from Amherst College in 1997, an MD from Albany Medical College in 2002 and a Ph.D. in Biomedical Engineering from Boston University in 2010. His dissertation research focused on modeling intra-cardiac robots for minimally invasive pediatric surgeries, and he has since co-authored a book chapter on predictive medical analytics.

Jesse has won several academic awards, including the graduate student Golden Apple Teaching Award, the Boston University Graduate Engineering Entrepreneurial Design Competition award, and the 2010 IEEE Transactions on Robotics Best Paper Award. He is currently an adjunct staff member at Boston Children’s Hospital and maintains a pediatrics practice in nearby Lexington, Massachusetts.


Etiometry Scientific Advisors

Dr. Peter Laussen, MBBS | Scientific Advisor

Dr. Peter Laussen graduated from Melbourne University Medical School and completed fellowships in anesthesia and pediatric critical care at the Austin Hospital and Royal Children’s Hospital in Melbourne before joining the Cardiac Anesthesia Faculty and the Division of Cardiac Intensive Care at Children’s Hospital Boston. He was later appointed Chief of the Division of Cardiac Intensive Care in the Department of Cardiology and as a Professor of Anesthesia at Harvard Medical School. In addition to clinical and teaching responsibilities, he led a large clinical research program focusing on the perioperative management of newborns, infants, children and adults with critical congenital and acquired heart disease.

In 2012 Peter was appointed Chief of the Department of Critical Care Medicine at the Hospital for Sick Children in Toronto. His other leadership roles at the hospital include being co-chair of the Mortality & Morbidity Committee and membership on the Medical Advisory Committee, the Clinical Operations Council and the Quality Management Council for the hospital. Peter is a Senior Associate Scientist in the Research Institute at Sickkids, and Professor of Anesthesia at the University of Toronto. He is also a co-founder of the internationally renowned risk management symposiums Risky Business, which brings together leaders in high-risk industries to discuss ways of improving the safety and quality of health care.



Dr. Melvin C. Almodovar, MD | Scientific Advisor

Dr. Melvin Almodovar joined Johns Hopkins All Children’s Hospital as Chief of Cardiovascular Intensive Care in September of 2015 from Boston Children’s Hospital, where he served as Medical Director of the Cardiac ICU since 2006. At All Children’s Hospital he also serves as the Medical Director of the Cardiovascular Intensive Care Unit and is Medical Director of the Extracorporeal Life Support Services.

Melvin has a pending academic appointment with Johns Hopkins School of Medicine. A pediatric cardiologist and cardiac intensivist, Melvin has been actively involved in the design and implementation of ICU-focused data collection and analytics systems to enhance patient safety and support clinical care, research and training in the critical care environment. His research includes development of innovative methods to track and intervene in critically ill patients whose trajectories are deviating from expected patterns, with the goal of developing real-time, actionable predictive models from continuous, high-frequency data streams.
